Driving system and operation method for driving device of fast reactor control rod driving mechanism

Abstract

The invention discloses a driving system and an operation method for a driving device of a fast reactor control rod driving mechanism. The embodiment of the invention provides the driving system whichcomprises a first driving device, a second driving device, a control module and a power supply module. The first driving device is arranged to control the first motor to drive a main shaft of a control rod driving mechanism to drive a control rod to move or suspend the control rod at a target position, the second driving device is arranged to control a second motor such that the second motor drives a gripper of the control rod driving mechanism to be connected with or separated from the control rod; only one of the first motor and the second motor is allowed to work at one time; the first driving device is used for independently controlling each phase of the first motor; and the second driving device independently controls each phase of the second motor. According to the driving system, the improvement of the operation reliability of a nuclear power plant is facilitated. The embodiment of the invention also provides the operation method of the driving device for the fast reactor control rod driving mechanism, the online maintenance of the driving device can be realized, the operation is simple, and the maintenance difficulty is low.

Description

technical field [0001] The invention relates to the technical field of nuclear power control rod driving mechanism, in particular to a driving system and an operating method for a driving device of a fast reactor control rod driving mechanism. Background technique [0002] The control rod drive mechanism is the actuator of the reactor rod control and rod position indication system and the power regulation system. It can realize the lifting, lowering and maintaining of itself and the control rod components connected to the lower part according to the instructions of the system, so as to realize the reactor start-up, Increase reactor power, reduce reactor power, maintain reactor current power operation, reactor refueling, and reactor shutdown. [0003] The drive device of the control rod drive mechanism drives the control rod drive mechanism to move. When the driving device of the control rod driving mechanism fails, it cannot drive the control rod driving mechanism, so that ...

AI Technical Summary

Problems solved by technology

When the driving device of the control rod drive mechanism fails, it cannot drive the control rod drive mechanism, so that the control rod drive mechanism cannot perform the intended movement of the control rod, or cannot maintain the movement of the drive control rod being performed

For example, the control rod drive mechanism is driving the control rods to move upwards. At this time, the drive device of the control rod drive mechanism fails, so the control rods cannot continue to move upwards, which affects the normal operation of the reactor.
